IMPROVEMENT IN GAS DROP-LIGHTS.

Specification forming part of Letters Patent No. 195,054, datedSeptember 11, 1877 application filed l May 9, 1877.

To all whom it may concern Be it known that I, WILLIAM B. S. TAYLOR, ofthe township of Westfield, in the county of Union, State of New Jersey,have invented a certain new and useful Improvement in the Manufacture ofwhat are known as Drop- Lights and Suspension Light Chandeliers; 7 and Ido hereby declare that the following is a full and correct descriptionthereof, reference being made to the annexed drawings and the letters ofreference thereon.

The nature of my said invention is such an arrangement and applicationof exible tubing to such drop-lights or chandeliers as will protect thetubing from injury by unnecessary 'coiling or rubbing, and the heat ofthe lights when the chandeliers or drop-light is in use, and will carryit out of the way when it is not in use.

I am aware that exible tubing has been used before in makingsuspension-light chandeliers; but it has always been placed where theheat of the lights acted upon it so powerfully that no exible tubingcould be made which would resist it and remain serviceable for anyconsiderable length of time. Besides, it was either coiled up in ahollow ball or worked over rollers, or in some way was subjected to somuch friction and pulling that its speedy destruction was madeinevitable. For this reason the use of fiexible tubing in connectionwith such drop-lights and suspensionlight chandeliers has beenreluctantly abandoned by gas-fixture makers, and different kinds ofjointed and sliding devices substituted for the purpose of conveying thegas from the stationary part to the movable or suspending part of suchfixtures. Such substitutes are necessarily more or less defective fromtheir nature, it being impossible to make metal joints or slides sotight as never to leak any gas and yet have them work freely and easily,especially when heated.

In my improved method of constructing such chandeliers and drop-lightsthe tubing is always to be attached to the lower parts both of thesuspending and of the stationary parts of the fixture, and is allowed tohang or is festooned in a manner agreeable to its nature.

In accompanying drawing, Figure l is a perspective view of asuspension-light chandelier, showing the light or lamp proper elevated.Fig. 2 is a side view of part of the chandelier, showing the light drawndown.

A is the large oval ring usual in` this class of fixtures; E, thegas-conducting tubes and B, lateral armsV carrying burners a. All theseparts are rigidly connected, and constitute the stationary portion ofthechandelier. Thelight or lamp C, having the outwardly and upwardly curvedtubular arms D D, is the movable part ofthe chandelier, the same beingvertically adjustable, with reference to the ring A, in consequence ofits suspension by chains H passing over pulleys J, and havingcounter-balance weights I attached.

The lamp C is connected with the rigid metal tubes E by means of theelastic flexible tubing G, which is shown attached at its respectiveends to collars or tubularv projections of the arms B, and to the outerends of tubes or lifting-pipes D. The latter may in some cases bedispensed with, and the flexible tubing G attached'directly to the lowerpart of the body of the lamp C.

The cross-bars b, which are attached to the ring A, limit the upwardmovement ot' the lamp O, Fig. l, and the chains H limit its adjustmentin the opposite direction, Fig. 2, by reason of the weights I cominginto contact with the cross-head in which the pulleys J are pivoted. Thetubing G is thereby prevented from being stretched or strained in theadjustment of the light higher or lower.

It will also be seen that said tubing G is attached to the xed orimmovable part of the chandelier at a point which precludes injury fromthe heat of the light, which is the inevitable result when such tubingis attached and suspended directly above the light, as usual heretofore,and is likewise not injured by wear, by reason of being wound in a coil.

The lifting-tubes D serve to suspend the inner ends of the tubing G, sothat when the light is raised, Fig. 1, the tubing will be, as it were,festooned or suspended in graceful curves, but always out of the sphereof the active and permanent injury of the heat.

The gas consumed in light C passes through tubes E, and is admitted totubing G by the regulating-cocks F.

the stationary chandelier-frame, of the curved goose-neck pipes D D,rigidly attached to the body of the lamp or light C, and extendingupward and outward, as shown, and the short pieces of flexible tubing Gattached to the lower ends of the part E, and the weighted chains forsuspending said light, as set forth, whereby, when the light is raised,the tubing is suspended in the manner specified.
